Hall of Heavenly Kings, also called Devaraja Hall, is the former entrance to Yongzheng's imperial palace. This hall is also called the Maitreya's shrine. In this hall, Maitreya always greets visitors with a smiling face.

On each sides of Buddha Maitreya, there is a sandalwood pagoda. On the pagoda stand many small Buddhist images which were symbols of longevity. Hence, the Longevity Pagoda.

On both sides of Maiteya's shrine are four fearsome looking Heavenly Kings or Celestial Guardians, two on each side.

The Buddhist theory goes that the earth is divided into four worlds: northern, southern, eastern and western. Each of the four worlds is guarded by one of the Four Heavenly Kings.

The Four Heavenly Kings are :

• Southern World Heavenly king: Zengzhang;
• Eastern world Heavenly king: Chiguo;
• Northern World Heavenly King: Duowen;
• Western World Heavenly King: Guangmu

Behind the shrine of Maitreya stands the statue of Weituo facing backwards to a large courtyard.
